Concerning dishes not used by the original owner or things packaged for selling, there is a machlokes who is obligated to tovel it as stated above.
I was given the idea by a posek, when I want to give a dish tray etc. for a gift, I should tovel it and put a small amount of clean dry) food on it FOR MY OWN USE, and then wrap and give the gift. (This won’t work for dish(es)given in original wrappings, or for a large set of dishes which is not practical to “use” every piece).
IMHO Too technical for someone who is Rav communication impaired
